Hi,
I have been converting an office over to VOIP based telephony and made a cool discovery. The TP-Link AC1750 (C7) is configured out of the box to handle multiple sip clients. I just hooked up a 2 line phone and an ata for a total of 3 SIP clients and they fired up the first time and work great.
I had no idea how unusual this was until I started rolling out phones to others who are behind dd-wrt, dd-wrt-voip, buffalo, linksys and others. With port forwarding, milkfish, and other tricks, I could get some of them to work, but generally, just one sip client. Yes, my setup is a little unusual in that I am a voip provider to home office clients without a VPN. pfsense+sipproxd are an awesome sip proxy. But just try and configure proxy to proxy communications, it ain't fun.
I haven't found anything about why the Archer C7 works so well, and its firmware exposes nothing regarding sip that I can find. I called tech support to ask them what other models share the same firmware and why does this work so well. The guy had no clue and could not understand how this was a problem.
Matter of fact this whole issue of multiple SIP clients and NATing seems to be largely ignored by manufacturers and reviewers. This is now a must have feature for me and for anyone else who wants a voip-based phone and fax or multiline phone.
So I need some routers, and will probably go with more C7s, but it is getting old. I am hoping that there are other guys who are exploring this as well and would love to know what works and what doesn't.
